I am not in this earth by chance. I am here for a purpose and that purpose is to grow into a mountain, not to shrink to a grain of sand. Henceforth will I apply all my efforts to become the highest mountain of all and I will strain my potential until it cries for mercy.

The moving power of mathematical invention is not reasoning but imagination.

@AlgebraicPavel Thanks for the comment. Could you explain me how vector $A*(A*randn(n,1))$ lies in a column span of $A^2$? I would be very much thankful to you. You may instead write in form of answer. I need this much help only.
